| 説明 | Dogtooth quartz, hematite, limonite and perhaps a trace of cinnabar, in this closeup of the spectacular stockwork at San Geronimo Creek. This is the sort of rock that made the mercury-miner's heart beat faster.Worth your while to click on the magnifier-glass here, in the full screen version. This is pretty amazing detail (imho) for a cell-phone photo. Country rock is plain old Cambria Slab graywacke sandstone. This is an in-situ field photo, just as I found it. Near the mouth of San Bernardo Creek, in Estero Bay State Park. |
